Objective

The railway industry in Indonesia has grown substantially in the past five years, with greater network and tracks length that will double in 2030. There has been a growing concern, however, that fatigue among front-line personnel have not been addressed satisfactorily. This study aimed at evaluating the degree of fatigue among passenger train drivers and suggested practical recommendations to the Indonesian Railway Company.

Method

A total of 32 train drivers (driving for about 4 h during the morning or afternoon shifts) agreed to participate in the study. Subjective and objective measures of fatigue (and sleepiness) were obtained prior to, during, and immediately following the end of a duty. Fatigue and driving performance were also determined based on (off-line) analysis of continuous video recordings of the drivers performing the duty.

Results

Fatigue generally increased as a function of time and, for some, 2 h of driving was sufficient in inducing substantial level of fatigue increase. Unlike the morning shift, the afternoon shift was characterized with increased undue fatigue and unacceptable level of performance decrements.

Conclusion

In general, fatigue was not found among train drivers working the morning shift. For these drivers, however, there were a couple of individuals with excessive levels of fatigue. The effects of fatigue were more apparent for the afternoon shift. This is possibly due to the degraded sleep quality as a result of split rest periods obtained prior to the duty. It is suggested in this study that the company pay a much closer attention to the work-sleep schedules, and to improve sleep quality by redesigning better sleeping arrangements.

印度尼西亚铁路行业的疲劳：一项关于旅客列车司机的研究

目标

印度尼西亚的铁路业在过去五年中大幅增长，网络和轨道长度将在 2030 年增加一倍。然而，人们越来越担心前线人员的疲劳问题并未得到令人满意的解决。本研究旨在评估旅客列车司机的疲劳程度，并向印度尼西亚铁路公司提出实用建议。

方法

共有 32 名火车司机（上午或下午班次驾驶约 4 小时）同意参与研究。在值班之前、期间和结束后立即获得疲劳（和困倦）的主观和客观测量值。疲劳和驾驶性能也基于对执行任务的驾驶员的连续视频记录的（离线）分析来确定。

结果

疲劳通常随着时间的推移而增加，对于某些人来说，2 小时的驾驶足以引起大量疲劳增加。与早班不同，下午班的特点是过度疲劳和不可接受的绩效下降水平。

结论

总体而言，早班列车司机未发现疲劳现象。然而，对于这些司机来说，有几个人过度疲劳。下午班的疲劳影响更为明显。这可能是由于在值班前获得分开的休息时间导致睡眠质量下降。本研究建议公司更加关注工作-睡眠时间表，并通过重新设计更好的睡眠安排来提高睡眠质量。
